The innovative layer of Ballistic Kevlar provides protection from possible shrapnel which may be present during a hazardous arc flash event. The generous fit makes wearing over work clothing easy with the large rise & seat which prevents binding. There is also a convenient cinch waist strap for adjustments. The wide pant legs make it easier to put on and take off your bib overalls even over size 13 work boots. A cinch strap located at the pant leg bottom provides a more comfortable fit around work boots, and there are no pockets to collect materials which may fall out & cause a deadly arc flash.
